My invention relates-to improvements in automobile radiatorfcond'ensers.

Theobj'ect of my invention is to provi dea novel condenser, adapted to be attachedto 5 boiling point. raised tQ-aconsideraable ex tent over that of the liquid containing'air and carbon dioxide gas, thus, with theelimt,

nation of these elements very much lessening the corrosion of-the metal of the-radiator and rusting of the interior of the water jacket.

; The invention provides 'further novel means permitting the discharge from the condenser of theFair and'carbondioxide gas and vapor while preventing the intake therein 5 from the atmosphere of'air for gases.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which illustrates my invention,

Fig. 1 is a reduced side elevation of my improved condenser shown mountea on an automobile and connected to the overflow pipe of. the radiator. V

Fig. 2 is an enlarged front elevation of one form of my invention which employs a collapsible soft rubber tub-e asavalve for closing the outlet and as a duct for conveying air and gas from the outlet to the atmosphere;

Fig. 4 is an enlarged section on the line 4- 1 of Fig. 2, showing the eduction tube collapsed and closing the outlet.

Fig. 5 is a view similar to Fig. 4', showing 5 the eduction tube expanded so as to serve an open duct.

Fig. 6 is a reduced top view of the container shown in Fig. 2.

the line '8 is a section on 7, the flexible valve strip being shown. on the cifofsedposition f (Fig. 9 is a viewsirn'ilarto Fig'fdfshowing the flexible strip e z ipanded so as lto forni with I the body of the container an openduot lead-j from theoutletto the atmosphere..-.j q l Similar -,characters of reference designate simih parts in the differentwiews.

Referring to Figs; 1 to 6, ldesignates body of liquid container comprising, pref-t erably an expansibjle bag of soft rubber; non; porous flexible fabric or other suitable material, the container being normally elosedvt o the atmosphere and adapted to hold liquid.

' Theflower end offithe body 1 has an inlet comprising a flexible tube, 2 of .soft rubber or other suitable material which is, adapted for attachment to the discharge lendoffa,

radiator overflow pipe 3 ofusuaht ypeg; the

upper endof which lfilminatesin the ra diator '4: directly under {the radiator capI5,

The body 1 at one side thereof above' the inlet tube at and near the top of the body has an. outlet 6 over which is disposed acol; lapsible tube 7, preferably of thinsoft rubber, one side ofsaidtube 7 being madev integral, asaby, cementing, withthebody 1. Said; side of ,thetube 7 has an opening Sithere through which registerswith the outlet For suspendingjthegbodyl it is provided at itsupper end with a tab 9.having afholev l0 therethrough adapted to. receive any supporting device, as apin ll 'lon the. dashboard.

.; 'lhfe other sideof the tuber? forms a valve comprising a; flexible strip normally; by; atmospheric pressure against -.the ;oppo

site side-so as to normailycl'o'se the opening 81 and the outlet 6. Upon a pressure injthe' container greaterf .than jatmospheric,., such pressure expands the tube 6,.as shown in Fig.

5", so as to'form an open iduct leading from the opening 8 and outlet 6 tothe atmosphere, thus permitting air, vapor anddioxidegas to escape from the container to the atmosphere.

Upon the internal pressure decreasing, the

side of the tube ,7fdistantfromthe body ,1 I

will collapse and again'close;;tlie opening 8 and outlet 6,. thereby preventing, air' or: gas

2Q. pressure on the outside $5. can be raised to a point considerably above entering the container through the outlet 6 and tube 7.

. In the operation of the device just described, the cap 5 of the radiator 4 is removed and the radiator is filled with the cooling liquid. The engine is then run so as to heatjthe liquid and cause it to expand and part of it with the air and gas will pass from the overflow pipe 3 through the tube 2 into the body 1, creating a pressure in the latter suflicient to expand the tube 7 and thereby permit air and dioxide gas to escape through the tube 7 to the atmosphere.

its previous boiling point without boiling, thereby enabling the engine to be run at a higher temperature without boiling the coolingli'quid.

.In the form of my invention shown in Figs. 7, 8 and 9, 12 designates a flexible expansible strip, composed of softrubber or other .suitable material integrally fastened, asby cementing, at one or more of its edge portions, as indicated in dottedlines in Fig.

7, and having a free portion 13 which forms a valve covering and normally closing the outlet f the expansible container body 1 to which the strip is attached.

When the pressure in the body 1 rises above atmospheric the expansible free portion 13 of the strip 12 will be expanded, as shown in Fig. 9, thus forming a duct 14 com nectin'g the outlet 6 with theatmosphere, whereby air, vapor or gas can escape from V the container to the atmosphere. As'soon as the pressure lowers in the radiator 4 and the container body 1, the portion 13 will retract to the closed position, shown in Fig.

To disconnect the condenser, as exemplified in either-of the forms shown in the drawing, it "is but necessary to lift the body 1 ofli' from the pin 11, and withdraw the inlet tube Qirom the overflow pipe 3. By reversing this simpleoperation the condenser may be replaced in operative position.

By closing the radiator 1 to the atmosphere by applying thereto the radiator cap 5, andattaching the inlet tube '2 to the overflow pipe'3, the radiator 4 is sealed against loss of water or alcohol unless the cooling liquid in the radiator is heated to its boiling point, and by reason of the use of my improved sealing condenser, which automatically effects theeliminating from the cooling liquid of most of the air and carbon dioxide gas, the boiling point of the cooling liquid is raised to a very considerable extent above that which it had when placed in the radiator, thereby enabling the running of the engine at a higher temperature without boiling of the cooling liquid than could be done without the employment of the sealing condenser.

By having the flexible strip comprising the valve held normally closed and the container normally held collapsed solely by atmospheric pressure, as shown and described, the valve will be opened by any internal pressure greater than the external atmospheric pressure, whereby the air and dioxidegas can be eliminated and discharged to the atmosphere, ashasbeen described, with a'minimum of running of the engine. v I do not limit my invention to the structures shown and described, as other-modifications, within the scope of the appended claim, may be made without departing from the spirit of inyinvention. I

What I claim is In an automobile radiator condenser, an expansible flexible closed container for liq-' uid normally held collapsed solely by exter nal atmosphere pressure and having an inlet adapted for connection with the discharge end of a radiator overflow pipe, and having abovesaid inlet an outlet, said container having a flexible strip integral therewith and having a free portion normally held solely by atmospheric pressure against said container and closing said outlet, said portion being movable by any pressure in said con-- tainer greater than atmospheric to uncover said outlet.

In testimony whereof I aflix my signature;
